Embodiment Construction

[0034] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0035] A method for calibrating the pitch-throttle curve of an oil-powered unmanned helicopter provided by the present invention includes:

[0036] S1. Control the work of the unmanned helicopter, and record the parameters of the pitch and throttle opening of the unmanned helicopter during work:

[0037] S11. Raise the pitch according to the set parameters during the working process of the unmanned helicopter;

[0038] Keep the engine of the unmanned helicopter at the rated operating speed at each pitch point, and maintain the set time T1;

[0039] S12. When the engine of the unmanned helicopter cannot maintain the rated operating speed or the throttle opening of the engine of the unmanned helicopter reaches the limit position, then control the unmanned helicopter to reduce the throttle opening and reduce the collective distance until the initial state of the unmanne...

Abstract

The invention relates to a calibration method for a pitch-throttle curve of an oil-driven unmanned helicopter. The calibration method comprises the following steps that S1,the unmanned helicopter is controlled to work, and the pitch and throttle opening parameters of the unmanned helicopter in the working process are recorded: S11, the pitch is increased according to set parameters in the workingprocess of the unmanned helicopter; an engine of the unmanned helicopter is kept at a rated working speed at each pitch point, and a set time T1 is kept; and S12, when the engine of the unmanned helicopter cannot keep the rated working rotating speed or the opening degree of a throttle valve of the engine of the unmanned helicopter reaches the limit position, the unmanned helicopter is controlledto reduce the throttle opening degree and the total distance until the unmanned helicopter is in an initial state, and a set time T2 is kept in the initial state of the unmanned helicopter; S2, the unmanned helicopter is controlled to stop; and S3, the pitch and the throttle opening degree of the unmanned helicopter are fitted into the curve. According to the calibration method for the pitch-throttle curve of the oil-driven unmanned helicopter and a system thereof, the pitch-throttle curve of the oil-driven unmanned helicopter can be accurately calibrated, the operation process can be effectively simplified, and the operation efficiency is improved.
